ROLLING-MACHINE.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed May 14, 1913. Serial No. 767,661.

To (:3! whom it may concern:

Be it known that I, WALTER ERBsLoH, of Barmen, Schoenenstrasse 1, Rhenish Prussia, Germany, a subject of the Emperor of Germany, have invented new and useful 1mprovements in Rolling- Machines, of which the following is a specification.

My invention pertains to rolling machines and particularly to that class of machines in which reversed rollers are employed. It consists in applying two drums, one on each side of the machine, so that the blank or strip may travel or reciprocate between the drums and pass through the rolls until the desired thickness is obtained, in arranging a clutch or coupling and a brake for each drum and inproviding cooling means for the surface of the rolls to permit a contmuous operation of the device without wear and tear.

My invention is fully shown on the accompanymg drawings on which- Fig'ure 1 is a side elevation of the comcontrivance 5. 6 is the metal blank or band of aluminium which is to be rolledfout in endlessstrips of thin dimensions and which according-to my invention travels to and fro between two drums 7, 8 on which the material is wound under strong tension, the rolls 3 and 4 changing their rotation accordingly with each stroke. The arrangement for reversing the'said rolls 3,

.4, is known and not part of my invention.

On both'sides of the rolls 3, 4, is placed a pressing device 10 consisting of a supporting or lower and of a movable or upper die 10 and 10 and a. pressing handle 10. This device serves also for guiding the blanks or strips in the prescribed position and to facilitate the entrance of the blank or strip between the rolls 3, 4. For driving the roll 3.

the following means are provided. On the motor or main shaft '11 is mounted a gear 12 meshing with a wheel 13 keyed to a shaft 14, said shaft carrying agear 15. This gear is in mesh with a wheel 16 forming part of a shaft 17, on which is also keyed a gear 18, that is in mesh with a gear wheel 19 and this wheel is fastened on the shaft of roller 3. For revolving said roller in the contrary direction the shafts 14, 17 carry the gears 15 and 16 and the pouplings' :r, m respectively extend from the wheels 16 and 16 as shown in Fig. 2. Shaft 17 is fitted with a pulley 21 which transmits motion by means of a belt 21 to a pulley 22 fitting loosely on a shaft'23, that is journaled in bearings 27. On the extreme end of this shaft is placed a pinion 24 meshing witha gear wheel 25, which is keyed on a shaft 26 that carries the drum 8. As will be easily understood by the foregoing the drum is revolved by the gear shown and described. The drum 7 on the left side of the standard 2 is revolved in similar manner by the pinion 18 driven from the wheel 19 and mounted on a shaft 17 the pulleys 21 22 belt 21*, and the gear wheels'24 25 the latter being mounted on shaft 26 which is guided in the bearings 27 According to the reversed rotation of the rolls 3, 4 the drums 7 and 8 have to change rotation and the driving means of one drum are put out of action 'or interrupted when the blank or strip is passed through the rolls 3, 4 and wound up on the free or empty drum, in which case of course the coacting drum is free to rotate to allow the blank or strip to be drawn off. For this purpose the shafts 26 and 26 of the drums- 7 and 8 which change their rotation are coupled with the shafts 23, 23 the pulleys 22, 22 of which move in opposite directions. This is effected in the present example by means of a spring coupling being advantageously adapted for the purpose of sud- .denly reversing the different shafts as will be understood from the following:

The pulley 22 is provided with a hub 29 around which is placed a coiled spring 30 which is connected with said pulley 22 and bears on a disk 31 which rotates with shaft 23 and may at the same time be moved thereupon to and fro. If now said disk 31 is moved by means of a lever 32 toward the pulley 22, the spring ispressed together, its

length is shortened and it is strongly pressed on the hub 29 so that shafts 23 and 26 respectively are caused to revolve and the drum 8 to wind up the blank or strip. The

' winding'of the blank or stripon the drum 8 is therefore effected in a correct manner I without formation of folds or breakage of v the edges.

3 drum 8, the pulley 22 will be put out of ac- After the blank has passed the tion by moving the disk 31 out of engagement therewith, by means of the lever 32.

the members 29, 30 and 31 in a manner similar to the way in which the pulley 22 cooperates with the shaft 23 by the corresponding members 29, 30, 31,'an'd 32, as hereinbefore described. The drum 7 is thus caused to revolve with the result that'thedrums 3 and 4, through which the blank is now passing, are moved in an opposite direct1on.; 'In order thatthe speed of rotation of the drum 8 may be regulated, each drum is fitted with a brake, comprising a disk 33, 33" respectively, a weighted lever 35, 35 and a brake block 34, 34 bearing on the disk 33, 33 It will be also clear that in the operation of the new.machine the blank can travel constantly or reciprocate between the drums 7 and 8 and pass the rolls 3, .4 until it is rolled out to the de sired thickness without being taken off from one of the drums and in consequence thereof much time issaved and a strip or band is obtained with smooth edges. In obtaining such an eifectit is however supposed that the rolls are cooled on their sur face in order to prevent the same from getting too much heated resulting from the constant revolution. a

In Fig. 6 I have shown a longitudinal v ew of the rolls, and from this fi re it Wlll be clearly understood that the. rolls are constructed to provide a substantially horizontal surface forthe-entrance of a blank, owing to the extreme pressure exerted on said rolls, at the time of the entrance of the blank. In Fig. 3 I have disclosed a construction I according to which the rolls are cooled with fresh air, which is thrown by means of' tubes 36, 37 upon the roll surface. Prefer-' ably the tubes are fitted at their ends with nozzles and connected with a fan, (not I shown in the drawing) and it will be clear that the constant air stream will sufliciently cool the surface of the rolls. While I have described the cooling mediumas air, it is of course apparent that I may employ liquid, air, water, chemicals, or the like, and if the blank under treatment requires heating, I may ofcourse employ a heating medium in combination with my cooling apparatus.

The modification of Fig. 3 is illustrated 5 in Fig. .4 which consists of chambers 38 and 39 attached to the rolls as shown. chambers 38 and 39 have perforations in the inner wallsthereof, the layer 40 of asbestos being inserted between the chambers and rolls. The cooling means is admitted by tubings 41 and the escape of said cooling means is through tubings 42.

Finally in Fig. 5 is shown a combination of inner and outer cooling, the chambers 38, v39 or the tubes 36, 37 being connected with The tubes 43, 44 and 45 which enter the center of the rollers as shown in Fig. 5. What I claim as my invention and desire to secure by Letters Patent is 1. In a metal rolling machine, a frame,

standards on the frame, pressing rolls carried 'by the standards, a drum at each end of the -frame, gearing for operating the drums, clutch :members for moving the drums into and-out-of operation,- whereby the direction of rotation of the drums and rolls is reversed.

2. In a metal rolling machine, a frame, standards supported centrally of the frame,

pressing rolls supported by the standards, a-

drum supported at each endof the frame,-

and on the same horizontal plane with the pressing rolls, means for operating the drums, means for communicating movement of the-drums to the pressing rolls, and clutch members for throwing the drums into and out of operation. V
